Re: [PATCH v10 0/2] MR2100: ntdll: Do not send data to port 0.

[Jason Beetham (＠beef331)]

Any insight into the best way to get the protocol inside `try_send`, presently I'm using `getSockOpt` as follows:
```c
    opt_err = getsockopt(fd, SOL_SOCKET, SO_TYPE, &protocol, &opt_len);
    if (!opt_err && protocol == SOCK_DGRAM && is_port0(&unix_addr))
```
This causes other tests to completely freeze up.
